IEPRovED FIRE-ESCAPE digs tlgehule referat it tu time More ttmtmxhmaking'aatt at tigt same.

TO ALL WHOM IT MAY GONGERN Be it known that I, JRGEN L. JRGENS, of NewOrleans, parish of Orleans, and State of Louisiana, have invented a newand useful Improvement in Fire-Escapes; and I do hereby declare thatthefollowing is a full, clear, and exact description thereof, which willenable others'skilled in the Vart to make and use the same, referencebeing had to the accompanying drawings, forming part of thisspecification, in which-'- Figure l represents a side elevation of myimproved attachment, with a part broken away, and

Figure 2 represents aplan view of the carriage.

Similar letters of reference indicate like parts.

The object of this invention is to provide a convenient, cheap, andreliable fire-escape for buildings.

It consists of a car, provided with axles, made adjustable in thedirection of the length of the same, and connected together by a shaft,having a right and left-hand screw-thread, by which the said axles maybe expanded or contracted, as it is moved up or down inclined waysplaced outside of the building, convenient to the windows of the same,to admit of the inmates of the building entering the ear as it is passeddown from one window to another. a

A represents the carriage, provided with grooved wheels, B, the axles ofwhich are supported adjustably Y in the slots C, in the sides of thecarriage.

The axles are connected together by a shaft, D, provided with a rightand left-hand screw, by the turning of which they may be moved to orfrom each other.

The said shaft is provided with a piuion-spur wheel, and cranks foractuating it'.

Eend E represent inclined ways or tracks, whereon the carriage isintended to be moved up and down, provided at the side of a house in asuitable position to admit the carriage to pass some of the windows indescending, affording the inmates an Opportunity to escape into it iutimes of danger by fire.

The square ends, F, of the carriage are intended to work against theguides Gr, to prevent the cud of the carriage from moving irregularly.

The carriage may be' raised by cords and weights, or .by any othersuitable means, and maintained at or near a window ready foruse, orthere may, if preferred, be provided as many carriages as there arewindows in the path of the guides. Each carriage will, to some extent,represent the appearance of a balcony.

When it is desired to make use of a carriage for descending, the samemay bereadily accomplished by turning the screw-shaft in the rightdirection to dpaw the' axles together, as will be readily understood.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent- The carriage A, provided with the adjustable groovedpulleys B, and operating shaft D, in combination A, with the inclinedways E E, substantially as and for the purpose described.
